False:  The sun does not make acne better. “Contrary to popular belief, sunbathing makes zits worse, not better,” Bank says. “The initial, temporary drying effect and the blemish-concealing tan may fool you, but UV rays actually stimulate oil production.” What’s more, the sun’s rays also thicken the outer layer of your skin, which blocks your pores and leads to breakouts.

Always practice sun safety by limiting time in the sun, especially between the hours of 10 am and 4 pm. Wear a hat and protective clothing, and choose a broad-spectrum sunscreen with an SPF of 30 or higher.
